Description

TECHNICAL FIELD

[0001] The application relates to the technical field of mixers, in particular to a cement mortar mixer for concrete production. BACKGROUND

[0002] In order to compare the quality and performance of different cements fairly and accurately on a global scale, it is necessary to eliminate variables in the testing process. The most critical link is the preparation of test samples (cement mortar test blocks), and the cement mortar mixer is designed to achieve this standardization. It strictly follows international (such as ISO 679) and national (such as GB / T17671) standards to ensure that the time, speed, sequence and method of each mixing are completely consistent, and it is used for quality inspection of cement leaving the factory, acceptance inspection of cement entering the factory, quality sampling or arbitration inspection of cement used on site, research on cement materials, development of new formulations, evaluation of admixtures, third-party certification, arbitration inspection and market sampling, and has extremely strict regulations on mixing speed (low / high), mixing time (each stage is accurate to seconds), and feeding sequence (water->cement->standard sand). The prepared cement mortar must be highly uniform and cannot have clumps or segregation, otherwise it will seriously affect the subsequent test block molding and strength test results. The performance (final strength) of the mortar prepared by the same standard in the laboratory, by different operators and at different times should be comparable. The special mixer is the key equipment to achieve this comparability. Although the mixer is mixing mortar (cement + standard sand + water), its mixing state (shear force, mixing effect) aims to simulate the process of cement paste wrapping aggregates in concrete, providing a basis for testing the cementing ability of cement.

[0003] The operator needs to add standard sand uniformly into the mixing pot within a specified time, and the speed, uniformity and timing of this action completely depend on the manual operation of the operator, which is one of the largest sources of human error in the process.
